How can I implement global error handling in Vue 3 with Axios?

You can set up global error handling in Vue 3 by using Axios interceptors. This allows you to catch errors for all requests.

Can you show me a code example of how to do that?

Sure! You can add an interceptor like this:

import axios from 'axios';

axios.interceptors.response.use(
  response => response,
  error => {
    // Handle the error
    console.error('An error occurred:', error);
    return Promise.reject(error);
  }
);

What if I want to show a notification when an error occurs?

You can integrate a notification library like Vue Toastification. In the error handler, you can trigger a toast notification to inform the user.

That sounds great! Can you provide an example of that?

Absolutely! Here’s how you can modify the error handler:

import { toast } from 'vue-toastification';

axios.interceptors.response.use(
  response => response,
  error => {
    toast.error('An error occurred: ' + error.message);
    return Promise.reject(error);
  }
);
